SHEET-DELIVERY APPARATU s FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Application filed August 28, 1886.

To all whom it may concern:

Be it known that I, WALTER Soorr, of Plainfield, in the county of Union and State of New Jersey, have invented an Improve ment in Sheet-Delivery Apparatus for Printing-Machines, of which the followingis aspecifieation.

In my present improvements the web of paper after it has been printed passes in between the cutting-cylinders. The female cutting-cylinder has pins immediately behind the cuttinggroove, so that the sheet is carried around and remains upon the cutting-cylinder, and a second sheet is laid upon the first sheet, so thatthe cutting-cylinder becomes also an imposing-cylinder, and there are discharge-fingers that throw off the advancing ends of the sheet at the proper time to be taken by grippers and delivered to belts or tapes that convey the imposed sheets to the folding or other delivery apparatus.

In the drawings, Figure 1 is a vertical section representing my-improvements. Fig. 2 is a partial plan of the same. Fig. 3 is a sec tion of portions of the female cutting-cylinder and delivery-cylinder, illustrating the operation of the discharge-fingers and grippers of the respective cylinders.

The web of paper passes between the typecylinder and the impression-cylinder 2, and then between the male cutting-cylinder 3 and the female cutting-cylinder 4. At 5 is the 'knife, and at 6 the grooved slot of the female cutting-cylinder, and in the surface of this slot are the impaling-pins 7 ,behind the groove. The cylinders 2, 3, and 4 are rotated by the gearing a, a a and a.

The discharge-fingers 9 extend out from the shaft 10, and their ends are adjacent to the impaling-pins 7. arm at the end of the shaft 10 to raise the discharge-fingers, and this cam is brought into position foraction every second sheet by the eccentric 14 and connection 15, or other suitable device.

The cylinder is at a slight distance from the cutting-cylinder 4, and the gear-wheels a a, that connect the cylinders, are slightly larger,

so that the surface speeds remain the same,

50 and around the cylinder 20 pass the belts or tapes 21,that are led over the rollers 22 23 24,

The cam 12 acts against the Patent No. 361,028, dated April 12, 1887.

Serial No. 212,048. No model.)

and the endless tapes or belts 25 pass over the rollers 26, 21,27,and-28,and are pressed closely against the cylinder 20 at one side, and are grippers upon the cylinder 20,that are opened by the cams 31 and 32 acting upon arms 46 of the gripper-shaft 47, and there are springs to close said grippers, as usual.

It is now to be understood that two or three sheets can be imposed upon the cylinder 4; but the grippers 30 cannot grasp the same until the discharge-fingers 9 press the advancing end of the sheets off the impaling-pins and into the path of the grippers, and said grippers closing hold the sheets and transfer them from the cylinder 1 to the cylinder 20,and said grippers carry the sheets around until they are received between the ranges of tapes 21 and 25, and then the cam 32 opening the grippers allows the sheets to be taken away by said belts 21 and 25, and over the roller 24 to any suitable folding and delivering apparatus.

This apparatus is especially adapted to book and job work, because the sheets are imposed with great accuracy one upon the other.

There may be a second set of gripper-fingers at on the cylinder 20, opposite the grippers 30,so that,in cases where the cam 12 is allowed to remain stationary, each sheet in succession will be raised from the impaling-pins and presented to a set of grippers by the deliveryfingers, and it is necessary to have sufficient space between the gripper-cylinder 20 and the cutter-cylinder 4 for the grippers to open and receive the sheet as delivered to the same by the fingers 9, for if this space were not provided the grippers 30 could not swing back to allow the end of the sheet to pass by them,and then swing the other way and close over and grip the end of the sheet.

I claini as my invention- 1. The combination,with the female cuttingcylinder, of impaling-pins upon such cylinder and adjacent to its groove and deliveryfingers, and means, substantially as specified, for operating the same every desired number of revolutions, and grippers, and a deliverycylinder sufficiently distant from the cuttingcylinder to allow the grippers to open and receive the advancing end or ends of the sheet or sheets, and one set of tapes around the delivery-cylinder, and an adjacent set of tapes around rollers for conveying the sheets away inder and grippers for receiving the advancbetween the sets of tapes from the deliverying ends of the imposed sheets whenpressed cylinder,substantially as set forth. away from the impaling-pins, substantially 2.
